Title: Wire dot printing head
Inventor: KAMIMURA KATSUYA
IPC: B41J2/27
Filed: 1986-06-17
Abstract: PURPOSE:To improve the life of the title head by preventing the characteristic deterioration due to the wear of a residual sheet, by a method wherein a beveling part or a notched part is formed on the core side of an armature and the contact point with the residual sheet is made to be the supporting point of the armature. CONSTITUTION:The contact point of the circular arc of the beveling part 12a formed at the corner part on the plate spring side and the core side of the corner part of an armature 3 with the residual sheet 10 is positioned inside the corner part 5a of a core 5 to have the function as the supporting point 9a of the armature 3. The contact point as the supporting point 9a moves along the circular arc of the beveling part 12a being followed by the very little reciprocating rotation centering the supporting point 9a at each frequency and besides, moves lengthwise on the residual sheet 10. Therefore, its abrasion resistance property is improved by preventing the centralization of a load to the residual sheet and its life can be prolonged.

Filed: 1980-10-07
Abstract: PURPOSE: To prevent the lining from generation of its eccentric wear and noise in such a way that a multitude of holes which are penetrated from the surface to the back face of a backing plate are arranged in specific condition, difference in the temperature is decreased between the central part and the peripheral parts of the lining.  
     CONSTITUTION: In a pad1 which is integrated in such a way that lining 3 is glued on the surface of a backing plate 2, and a groove 4 is arranged at the central part, a multitude of holes 5 are made penetrating through the backing plate 2 and the lining 3. The holes 5 are radially so that they are denser in proportion to be closer to the central part taking the central part of the lining 3 which is worst in dissipation of heat as its center, and they are sparser in proportion to be closer to the peripherl parts or to the groove likewise on both sides. Thus, the dissipation of heat the central parts of the lining 3 can be made favorable, and difference in temperature of the lining 3 can be reduced at the central parts and the peripheral parts. In consequence, eccentric wear on the lining 3 accompanied with temperature can be prevented, and generation of noise caused from rubbing the end edge of the lining 3 with the lateral side of a rotor when re-braking can be prevented.

Title: Twin symbol checking device
Inventor: FUKUSHIMA SHUNICHI
IPC: G06F17/21
Filed: 1988-06-07
Abstract: PURPOSE:To reduce omission of detection of wrong twin symbols by adding an interval discriminating means which discriminates whether the interval between twin symbols is proper or not. CONSTITUTION:An interval discriminating means 5 receives a pair of twin symbols (a left twin symbol and a right twin symbol) and their positions from a twin discriminating means 4. This pair of twin symbols are judged to pair by the twin discriminating means 4. The interval discriminating means 5 calculates the interval (characters) between the left twin symbol and the right twin symbol. The interval discriminating means 5 compares this interval with a preliminarily determined threshold; and when the interval exceeds the threshold, the means 5 judges the pair of twin symbols to be improper. When the interval is shorter than the threshold, the means 5 judges the pair of twin symbols to be proper. When the pair of twin symbols is judged to be improper, positions of twin symbols are outputted to a sentence display means 6.
